Comcast's NBC Buy Won't Bankrupt Cable Giant, But It's Odd, Wasteful and Dangerous

the rest of

This expensive purchase will give Comcast full control over NBC and all of its assets, including a film studio (Universal Pictures), an amusement park (Universal Studios), and one of the least successful networks on regular TV. In the

confirming the acquisition, Comcast said that this deal "solidifies" its position as a "leading media and technology company." "This is an exciting day for Comcast as we have agreed to accelerate the purchase of NBCUniversal," Brian L. Roberts, Chairman and CEO, Comcast Corporation, said in a company release. "…Our decision to acquire GE's ownership is driven by our sense of optimism for the future prospects of NBCUniversal and our desire to capture future value that we hope to create for our shareholders. … We believe we are in a strong and unique position to continue to grow and build value in our combined company." Those are some positive words coming from an executive who just spent more than $16 billion on a network that

Three other shows -- Smash, Whitney and Guys With Kids -- are "likely" to be canceled. 30 Rock, one of NBC's most critically acclaimed shows, experienced steep ratings declines over the past couple of seasons. NBC responded to these declines by canceling the series. Alec Baldwin (who played Jack Donaghy) told the network that he would

Even Up All Night, the Christina Applegate comedy that was supposed to bring huge ratings to NBC, is on TVByTheNumber's "likely to be canceled" list. Go On, Matthew Perry's latest sitcom, also benefited from an Olympic Games premiere, earning

Of those seven shows, only two of them -- Revolution and Chicago Fire -- are new. If these estimates are correct, it means that NBC was only able to save two or three new shows this season. (The third could be Go On, but that is still a toss-up.) What does Comcast hope to do with a $30 billion network (remember: Comcast paid $16.7 billion for the remaining 49 percent stake in the company) that can only produce a couple of successful shows per year? What will Comcast do with those shows when their ratings are far below the nearest competitor? Even the Olympic Games -- NBC's most prized sporting event -- are a risky, a money-losing venture. The network lost

on the Vancouver games in 2010. Analysts estimated that the company would lose another $100 million on last year's Summer Games in London, but NBC found a way to break even. "We are way ahead of where we thought we'd be," NBCUniversal chief exec Steve Burke told the
